Autoinfection in wheat leaf rust epidemics [PDF]

New Phytologist, 2008
Autoinfection (within-host inoculum transmission) allows plant pathogens locally to increase their density on an infected host. Estimating autoinfection is of particular importance in understanding epidemic development in host mixtures. More generally, autoinfection influences the rate of host colonization by the pathogen, as well as pathogen evolution.

Coffee Leaf Rust Resistance: An Overview

, 2023
AbstractCoffee is one of the most important cash crops and beverages. Several diseases caused by fungi, bacteria, and viruses can affect coffee plantations and compromise production. Coffee leaf rust (CLR), caused by the biotrophic fungus Hemileia vastatrix is the top fungal disease, representing a permanent threat to sustainable Arabica coffee ...

Resistance to Leaf Rust, Stripe Rust, and Stem Rust in Aegilops spp. in Israel [PDF]

Plant Disease, 2005
In all, 1,323 single plant accessions of Aegilops bicornis, A. kotschyi, A. longissima, A. ovata, A. searsii, A. sharonensis, A. speltoides, and A. variabilis collected from 18 regions in Israel and 2 adjacent regions in Lebanon and Egypt were evaluated for leaf rust (Puccinia triticina) and stripe rust (P.

Effect of Leaf Rust on Grain Yield and Yield Traits of Durum Wheats with Race-Specific and Slow-Rusting Resistance to Leaf Rust [PDF]

Plant Disease, 2006
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum) in many countries. We compared the effectiveness of different types of resistance in International Maize and Wheat Improvement Center-derived durum wheat germ plasm for protecting grain yield and yield traits.

Identification and Validation of a Major Quantitative Trait Locus for Adult Plant Resistance Against Leaf Rust From the Chinese Wheat Landrace Bai Qimai

Frontiers in Plant Science, 2022
Leaf rust caused by Puccinia triticina Eriks. (Pt) is a common disease of wheat worldwide. The Chinese wheat landrace Bai Qimai (BQM) has shown high resistance to leaf rust for a prolonged period of time; the infected leaves of BQM displayed high ...

The Underexplored Mechanisms of Wheat Resistance to Leaf Rust

Plants, 2023
Wheat leaf rust, caused by the obligate biotrophic fungus Puccinia triticina Eriks. (Pt), is one of the most common wheat foliar diseases that continuously threatens global wheat production. Currently, the approaches used to mitigate pathogen infestation include the application of fungicides and the deployment of resistance genes or cultivars. However,

Marker-Assisted Improvement of Bread Wheat Variety HD2967 for Leaf and Stripe Rust Resistance

Plants, 2022
The mega wheat variety HD2967 was improved for leaf and stripe rust resistance by marker-assisted backcross breeding. After its release in 2011, HD2967 became susceptible to stripe rust and moderately susceptible to leaf rust.

Seedling and Slow Rusting Resistance to Leaf Rust in Chinese Wheat Cultivars [PDF]

Plant Disease, 2010
Identification of resistance genes is important for developing leaf rust resistant wheat (Triticum aestivum) cultivars. A total of 102 Chinese winter wheat cultivars and advanced lines were inoculated with 24 pathotypes of Puccinia triticina for postulation of leaf rust resistance genes effective at the seedling stage.

Characterization of Leaf Rust and Stripe Rust Resistance in Spring Wheat ‘Chilero’ [PDF]

Plant Disease, 2018
Since 1984, the ‘Chilero’ spring wheat line developed by CIMMYT has proven to be highly resistant to leaf rust and stripe rust. Amid efforts to understand the basis of resistance of this line, a recombinant inbred line (RIL) population derived from a cross between Avocet and Chilero was studied.

The potential of hybrid breeding to enhance leaf rust and stripe rust resistance in wheat [PDF]

Theoretical and Applied Genetics, 2020
Abstract Key message Hybrid wheat breeding is a promising strategy to improve the level of leaf rust and stripe rust resistance in wheat. Abstract Leaf rust and stripe rust belong to the most important fungal diseases in wheat production. Due to a dynamic development of new virulent races, epidemics appear in high frequency and causes significant ...
